I hate saying this, because it makes me look all snobbish, BUT....
If the series is going to be mostly rehashing the old series but with live action? What's the damn point? It's just like when Disney remade Lion King nearly identically but with expensive CGI?
To me, Cowboy Bebop is one of the VERY few pieces of media that I would consider damn near perfect. It's like remaking Citizen Kane or The Godfather or Star Wars (A New Hope). There is no way this remake will reach the same levels as the original anime, and that opening hasn't given me much to say that it will be much different than the series, except a more conservative outfit for Faye.
